Abstract
A curable silicone is used to encapsulate porous, photoluminescing silica nanoparticles having three-dimensional, web-like structures. The encapsulation protects the silica nanoparticles, preserves their photoluminescent effect, and can be used as a coating. The composition is used to prepare articles of manufacture by casting it on a substrate such as glass or a silicon wafer and curing it. Special effects can be obtained by using a mask on the substrate prior to deposit of nanoparticles and curing the silicone matrix.
